CARDING DEVICE FOR ARTIFICIAL TEETH Filed Aug. 27, 1930 A TTORNE Y Patented May 10, 1932 UNITED STATES PATENT. OFFICE MYER CHAREN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO UNIVERSAL SYLVAN IA GABIDING- DEVICE FOR ARTIFICIAL TEETH Application filed August 27, 1930. Serial No. 478,009.

This invention relates particularly to stock cards upon which artificial teeth are mounted and transported by the manufacturer to the dealer-for sale to the dentist.

' It is well known to those familiar with the manufacture and sale of artificial teeth that it is necessary that the dealer carry in stock various sizes, forms, and shades of teeth, and that in order that it may be convenient-for the dentist to select the articular size, form, and shade of teethdeslred, it is customary to mount a number of teeth having the same characteristics, or teeth of a set upon cards or panels of suitable form andmaterial, from which they may be withdrawn by the dealer as selected by the dentist, and replaced by new stock from the manufacturer.

It is well known in carding-devices to provide in fixed relation to the mounting card or panel a plurality of individual tangs or tongues spaced apart and forming a permanent part of the base and to stamp, impress, or otherwise markthe card or panel with symbols or indicia denoting the grade, color, and the like of the teeth applied to such per-'- manent supporting devices, thus limiting the carding device to a particular grade of teeth.

It may be said to be the leading object of the present invention to overcome this limitation by providing a carding device with interchangeable means whereby not only endevice. I

Another object of the present invention is tire groups or sets of teeth may be readily applied to or removed from the card or panel but the symbols and identifying indicia may be also readily interchanged, thus greatly enlarging the field of usefulness of the carding to provide an efficient and relatively inexpensive mounting'card or panel equipped with a removable group of supporting tangs or tongues by which the artificial teeth are not only firmly held but from which the same mafy-be readily disengaged, either, singly or as a group, without scratching or otherwise marring of the'face of the mounting card or panel.

A further object of the present invention is to provide a carding deviceof the character stated in which a group of pendant tangs or rubber,

tongues are formed integral with an interchangeable slide capable. of endwise movement through the card or panel, whereby the spacing of or change of grade of teeth may be varied as desired without change of the card or panel per se, thus adding to fulness of the device.

the use- A still further object of the present inveni tion is to provide a carding device of the character stated havingacard or panel of wood, 7 or other non-metallic material grooved to receive a strip of metal having stamped therefrom a group of pendant tangs or tongues to engage and support tooth faclngs having a varying range of size and form. a A still further object of the present 'invention is to provide for a carding device a removable, elongated, metal strip having struck out therefrom a plurality of pendant tangs or tongues so shaped and proportioned that each constitutes a bowed, spring-like member for exercising constant pressure upon artificial teeth supported thereon which may vary in range of size and form.

Other andfurther objects of the present invention reside in the provision'of general details of construction and in the arrangement, combination, and connection of parts for attainingthe results sought by the foregoing objects. I

The invention consists of the novel construction hereinafter described and finally claimed. i

The. nature, characteristic features and scope of the invention will'be more fully understood from the following description taken in connection with the-accompanying drawings forming parthereof, and in which:

Fig. 1 is a view in perspective of a carding devlce embody ng the lnvention and illustrating the manner of inserting my novel tooth rack and identifying symbols with respect to a card or panel;

Fig. 2 is a face view of the parts shown in Fig. 1, with the tooth rack and identifying tooth facing the line 3- -3 of Fig. 1;

Fig. 8 is an end view of Fig. 6.

Forthe purpose of illustrating my inven .tion I have shown in the accompanying drawings one form thereof which is at present preferred by me, since .thesamehas .been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of iarranged'and organized and'that my invenitionis not limited to the'precise arrangement iandorganization of the instrumentalities as herein shown: and described.

:Referring 'to'th'e drawings in detail, the reference numeral 10 designates a card or panel of'rectangular configuration and made of iWOOd,:fibI'e, rubber, or other non-metallic Ematerial. .Adjacentits bottom and paralleling the lower edge thereof upon its 'front face 'is arranged a longitudinal slot or groove .11 which extends from end to end of the board or .panel andhas open ends. The slot or .groove llis undercut at 12, top and bottom, throughoutits'length to provide a track for slidably receivingan elongated thin metal artificial tooth :holding bar 12 having stamped therefrom a plurality of aligned, pendant, bowed spring tangs or prongs '13 which are preferably spaced an equal distance apart and extend throughout the length of the bar. *Each'tang or prong .13 at its place of connection withthe bar 12 has fillets '14 upon opposite sides of a tang or tongue 13 so that strength may be provided where'the tangs are bent outwardly from the bar '12. If the tangs or prongs were so stamped thatnthe prongs must be bent out- Wardly at a sharp angle with respect toathe :bar 12,.theitendency to'readily fracture the connecting parts would occur. Again, the fillets provide space between the outer face of the bar 12 and the upper partsof the'tangs orprongs topermitthe .grooves'in the lingual faces of artificial teeth 15 tobe pushed freely upwardly so that the bottoms of the teeth of the'tangs or prongs 13.' The tangs are pointed, andextend an appreciable distance in advance of the front face'of the card 'or panel 10. Thus, the facings 15 maybe readily attached tothe tangs .13 and are firmly held thereby-so astoberem'ovably inserted orrem'oved asa continuous line of teeth with color, or an entire line of facings may be interchanged, as is readily apparent.

The upper portion of the face of the card or panel 10 is provided adjacent the corners thereof with slotted openings 16 which are undercut-to provide upper and lower; grooves 17, see Fig. 3, to removably receive slides 18 of paper, celluloid, or the like, see Fig. 1, said slides bearing symbols or indicia employed to "identify the particular facings carded as to grade, "color, shade, or the like. Since the slides 18 may be readily removed and inserted'through the open ends of the openings 16 theslides may be interchanged at will to identify various facings as they may be changed upon the card or panel, thus addingto the-usefulness of the device.

What I claim is: Y

1. A carding device of the character stated comprising a non-metallic panel having a longitudinal slotted portion in the face thereof having undercut track-like formations and'having open ends, and. a metal'bar having struck out therefrom a plurality of pendant,.resilient tangs ffor artificialteeth removable reception, said'bar being arranged for endwisemovement through said'slotted .portion.

2. .A carding device of the characterstated comprising a non-metallic panel having a longitudinal slotted portion in the face thereof extendingfrom end to end of said panel and having open ends, and a metal bar'hav- 'ing struck out therefrom a plurality of pendant, resilient tangs for artificial teeth removable reception, said-barbeing arranged for endwise movement-through said slotted portion in interlocked, relation.

8. .A carding device ofthe character stated comprising a non-metallic panel having a longitudinal slotted portion in the face thereof and which slotted portion is undercut to retain ametal bar, said slotted portion havingopenends, and a metal bar having struck out therefrom a plurality of pendant,resilient pointed tangs for artificial teeth re- .movable reception,'said bar being arranged for endwise movement'through said slotted portion, said tangs beingbowed so as to be spaced laterally'from the panel face in inserted position of said bar.

4 A carding device of the character stated comprising a panel ofnon-metallic material having a horizontally disposed slotted portion extending from end toend of said panel andhaving open ends and upper and lower undercut portions to provide tracks, and a metal bar having stamped therefrom a plurality "of pendant, bowed, artificial teeth receiving tangs having pointed terminals, the .-juncture of each tang with said bar being formed with a fillet, said bar being arranged forend movement through'thetracks of said slotted portion.

:5. A carding device of the character stated comprising a panel of non-metallic material having a horizontally disposed shallow slotted portion extending from end to end of said panel and having open ends and upper and lower undercut portions to provide tracks, and a thin, flat metal bar or rectangular cross-section arranged to snugly fit said slotted portion, said bar having vstamped therefrom a plurality of pendant, bowed, spaced, resilient artificial teeth receiving tangs having pointed terminals, the juncture of each tang with said bar being formed with a fillet, said bar being arranged for end movement through the tracks of said slotted portion.
